Introduction: Tauopathies, including Alzheimer's disease (AD), feature abnormal accumulations of hyperphosphorylated Tau protein; however, their biomarker potential in traumatic brain injury (TBI) is not well-defined. This study investigated whether cerebrospinal fluid (CSF) phosphorylated Tau at threonine-217 (pTau-217) could serve as an early biomarker for severe TBI (sTBI).

Methods: CSF samples from 26 sTBI patients, collected between 6 and 240 h post-injury, and 19 healthy controls were analyzed using an optimized direct enzyme-linked immunosorbent assay (ELISA; sensitivity < 4.7 pg/mL) for pTau-217 detection, complemented by Western blot validation. Temporal analysis, ROC curves, and trajectory clustering were used for interpretation.

Results: CSF pTau-217 levels were significantly elevated in sTBI patients at 6, 12, 18, 24, and 48 h post-injury compared to controls (p …

Comparative Analysis Of Aav Serotypes For Transduction Of Olfactory Sensory Neurons, Benjamin D W Belfort, Johnathan D Jia, Alexandra R Garza, Anthony M Insalaco, J P Mcginnis, Brandon T Pekarek, Joshua Ortiz-Guzman, Burak Tepe, Hu Chen, Ascent-Pd Investigators, Zhandong Liu, Benjamin R Arenkiel

Olfactory sensory neurons within the nasal epithelium detect volatile odorants and relay odor information to the central nervous system. Unlike other sensory inputs, olfactory sensory neurons interface with the external environment and project their axons directly into the central nervous system. The use of adeno-associated viruses to target these neurons has garnered interest for applications in gene therapy, probing olfactory sensory neuron biology, and modeling disease. To date, there is no consensus on the optimal AAV serotype for efficient and selective transduction of olfactory sensory neurons

Tuberculosis drug trials are primarily designed to identify antibiotic regimens with the strongest potency to kill Mycobacterium tuberculosis. However, microbiologic cure is not synonymous with improved health and recovery. Beyond antimicrobial efficacy, parameters such as morbidity and mortality related to lung function, cardiovascular health, and cancer should be prioritized. This narrative review emphasizes the critical need to emphasize clinical outcomes as much, if not more, than microbiological endpoints. We examine the underlying pathophysiological mechanisms and determinants of non-microbiological outcomes in tuberculosis, providing a synthesis of current knowledge. While there is growing evidence for some biomarkers to risk stratify TB …

Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical-centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity. At the same time, widespread departures from historical fire regimes have limited the ability to sample diverse fire histories. We examined 2 areas in California's Sierra Nevada (USA) with active fire regimes to study the responses of bird, plant, and bat communities to a broad spectrum of temporal, spatial, and severity patterns of fire. Bird and plant species richness peaked …

Novel agents targeting upregulated signaling pathways are needed to improve outcomes in T-cell acute lymphoblastic leukemia (T-ALL), since conventional cytotoxic chemotherapy regimens have reached the limits of tolerability. We identified upregulated, targetable signaling pathways common to both human T-ALL samples and a KrasLSL-G12D/+.Mb1Cre/+ murine model of T-ALL. We found the NAMPT inhibitor FK866 had the greatest cytotoxicity of a panel of small molecule inhibitors tested in human and mouse T-ALL cell lines, and in patient derived xenograft (PDX)-expanded T-ALL patient samples. We subsequently tested FK866 in vivo in PDX mouse models of T-ALL, and found that it significantly reduced the …

Faculty, Staff and Students Publications

The complex interactions between parasites, their hosts, and associated microbiota hold significant implications for host health and disease outcomes. Helminths like Ascaris lumbricoides and Ascaris suum can significantly alter the host's intestinal microbiota, affecting both parasite biology and host pathology. Despite extensive research on host-microbiota changes due to helminth infections, the study of helminth-associated microbiota remains limited. This study aims to characterize the microbiota associated with Ascaris larvae and surrounding host tissues at distinct developmental stages (day 4, day 8, day 14), during larval migration through the liver, lungs, and intestine, and its impact on the host's microbiota in a …

Histone Deacetylase 6 Inhibition Promotes Microtubule Acetylation And Facilitates Autophagosome-Lysosome Fusion In Dystrophin-Deficient Mdx Mice, Akanksha Agrawal, Erin L Clayton, Courtney L Cavazos, Benjamin A Clayton, George G Rodney

Faculty, Staff and Students Publications

Aim: Duchenne muscular dystrophy is a progressive muscle-wasting disease caused by mutations in the dystrophin gene. Despite progress in dystrophin-targeted gene therapies, it is still a fatal disease requiring novel therapeutics that can be used synergistically or alternatively to emerging gene therapy. Defective autophagy and disorganized microtubule networks contribute to dystrophic pathogenesis, yet the mechanisms by which microtubule alterations regulate autophagy remain elusive. The present study was designed to uncover possible mechanisms underpinning the role of microtubules in regulating autophagy in dystrophic mice.

Methods: Mdx mice were also supplemented with Tubastatin A, a pharmacological inhibitor of histone deacetylase 6, and …

Faculty, Staff and Students Publications

Extreme hypertriglyceridemia, defined as triglyceride (TG) levels ≥1000 mg/dL, is almost always indicative of chylomicronemia. The current diagnostic approach categorizes individuals with chylomicronemia into familial chylomicronemia syndrome (FCS; prevalence 1-10 per million), caused by the biallelic combination of pathogenic variants that impair the lipolytic action of lipoprotein lipase (LPL), or multifactorial chylomicronemia syndrome (MCS, 1 in 500). A pragmatic framework should emphasize the severity of the phenotype and the risk of complications. Therefore, we endorse the term "persistent chylomicronemia (PC)" defined as TG ≥1000 mg/dL in more than half of the measurements to encompass patients with the highest risk for …

Faculty, Staff and Students Publications

We have previously shown that mice with a loss of C-type lectin-like type II (CLEC2), which have lymphatic dysfunction due to the role of CLEC2 in platelets for maintaining separation between the venous and lymphatic system, develop lung tertiary lymphoid organ (TLO) formation and lung injury that resembles an emphysema phenotype of chronic obstructive pulmonary disease (COPD). We now sought to investigate whether and how TLOs in these mice may play a pathogenic role in lung injury that is relevant to human disease. We found that inhibiting TLO formation using an anti-CD20 antibody in CLEC2-deficient mice partially blocked the development …
